Hello,
I have noiticed a change of behaviour from
rc3 to rc4 which I consider a bug.
I have wrote a junit test case that reveals the behaviour.
Recall that Paper has a collection of Qualifiers,
which is mapped to an indirection table.
The collection-descriptor (in repository_junit.xml)
has auto-update="false".
public void testStorePaper()
{
String now = new Date().toString();
Paper paper = new Paper();
paper.setAuthor("Jonny Myers");
paper.setDate(now);
Qualifier qual = new Topic();
qual.setName("qual " + now);
paper.setQualifiers(Arrays.asList(new Qualifier[] {qual}));
broker.beginTransaction();
broker.store(paper); // will appear in the database
broker.store(qual); // will appear in the database
Identity paperId = new Identity(paper, broker);
broker.commitTransaction();
// now the indirection table CONTENT_QUALIFIER is still empty.
broker.clearCache();
broker.beginTransaction();
Paper retPaper = (Paper)broker.getObjectByIdentity(paperId);
System.out.println("retrieved: " + retPaper);
List qualifiers = retPaper.getQualifiers(); // should contain the above
qual.
System.out.println("ret qualifiers: " + qualifiers);
assertEquals(1, qualifiers.size()); // fails, qualifiers is empty !
broker.commitTransaction();
}
I can work around that problem by setting auto-update="true", but I do not
want to do that (and I did not have to in 1.0.0 rc3), because I want to
exploit the performance gain I have when using
PersistenceBroker.store(Object obj, ObjectModification modification)
rather than
PersistenceBroker.store(Object obj),
and when I use auto-update="true", the object qual seems to get stored
automatically.
Can someone verify that this is a bug, or is it intended change of
behaviour?
In the latter case, does the combination of an indirection-table
with auto-update="false" make sense at all?
BTW, I have not been able to reproduce the problem with the bi-directional
m-n-relation Project <-> Person.
Regards,
Olli
